If you have an account that is generating a message “account is locked for XXX seconds” you will need to do the following to unlock it.
In customers phone go into SETTINGS then select APPS and then the RSC+ App.
Touch on STORAGE then CLEAR DATA.
This will clear their RSC+ App.
Log in to RSC+ and it will only show DEMO panel.
Create a new account and SCAN the UID.
Enter User code and connect.
All should work as normal.
If they still cannot log in, try reset password.
This should resolve the issue.
